Detailed Description

The Eigensolver is a templated virtual base class that defines the
basic interface that any eigensolver will support.

This interface is mainly concerned with providing a set of eigensolver
status method that can be requested from any eigensolver by an
StatusTest object.

C++ includes: AnasaziEigensolverDecl.hpp

virtual
std::vector<int> Anasazi::Eigensolver< ScalarType, MV, OP
>::getRitzIndex()=0

Get the index used for indexing the compressed storage used for Ritz
vectors for real, non-Hermitian problems.

index has length numVecs, where each entry is 0, +1, or -1. These have
the following interpretation: index[i] == 0: signifies that the
corresponding eigenvector is stored as the i column of Evecs. This
will usually be the case when ScalarType is complex, an eigenproblem
is Hermitian, or a real, non- Hermitian eigenproblem has a real
eigenvector.

index[i] == +1: signifies that the corresponding eigenvector is stored
in two vectors: the real part in the i column of Evecs and the
positive imaginary part in the i+1 column of Evecs.

index[i] == -1: signifies that the corresponding eigenvector is stored
in two vectors: the real part in the i-1 column of Evecs and the
negative imaginary part in the i column of Evecs
